Fire Fighting & Protection

We offer a complete product range of Medium Velocity Water Spray System and Co2 Flooding System

Medium Velocity Water Spray System

Medium Velocity Water Spray Nozzles has an external deflector, which discharges water in a directional cone shaped pattern of small droplet size. The water is uniformly distributed over the surface to be protected. The nozzle is used in deluge water spray system for special hazard fire protection application. As the design and intent of specific water spray system may vary considerably, a MV nozzle is made available in several combination of orifice sizes and spray angles.

The minimum desirable pressure to achieve a reasonable spray pattern is 1.4 Kg./Sq.cm. The water distribution pattern as shown in the graph in following pages is at an average pressure of 2.0 Kg/Sq.cm. The change in pressure between 1.4 to 3.5 Kg./sq.cm. does not affect considerable change in spray angle. The spray pattern shown is with indoor application. System designer must consider wind velocity while designing the system for outdoor application. Field obstruction if any affecting the spray pattern of the nozzle must also be considered. The nozzle may be oriented to any position which is deemed necessary to cover the hazard.

Some of the areas where this system is widely used are:

	Horizontal storage vessels (like LPG Bullets, NH3 storage tanks etc.)
	Vertical storage vessels (like benzene, xylene, toluene tank age etc.)
	Spherical storage vessels (like LPG bullets, spheres etc.)
	Spot protection (Protection of selective areas/equipments)

Maintenance

Use Teflon tape or soft thread sealant onmalethread of the nozzle. The nozzles must be hand tightened into the fitting. LIFECO make wrench must be used to tighten the nozzle unit into the fitting. Excessive tightening torque may result into serious damage to nozzle arms and the deflector which may affect spray pattern of the nozzle andit'sperformance.

Co2 Flooding System

Co2 at atmospheric pressure is a colorless, odorless and electrically Non Conductive inert gas, It has high expansion ratio which facilities rapid discharge and allows three dimensional quick penetration in the entire hazard area. Made from premium quality components, this system's importance lies in the fact that it has high efficiency to extinguish fire by reducing the oxygen content of the protected area below the point where it can support combustion. Designed to withstand every climatic conditions, these devices are widely used in following area of applications:

Transformers, Power Generators, Machinery Spaces, Ships Holds, Electrical Equipments, Chemical Equipments, Chemical Work & Stores, Switch Rooms, Electric Movers, Solvent Stores, Dip Tanks and Oil Cellars etc.

Description/Specification of Co2 Flooding System

We are engaged in offering a comprehensive range of qualitative Co2 flooding systems. These have high expansion ratio that leads to rapid discharge and facilitates three dimensional penetration of the entire hazard area in a fastest manner. Some of the advantages of Co2 system are:
